684 SCHOUW'S PHYTO-GEOGEAPHIC REGIONS. 



species of Oak, Dammar, Rhododendron, Berberis, Primula, etc., also 

 occur. Mean temperature, 37° to 66° F. Some European grains and 

 fruit are cultivated, along with Mountain Rice. 



9. The Region of the Asiatic Islands, Polynesian Flora (Rein- 

 wardt's Region). — This includes the mountainous districts of the islands 

 between the south7eastern Peninsula and Australia, to the height of 

 5500 feet above the level of the sea. Mean temperature, 66° to 84°. 

 Orchids, Ferns, and species of Ficus abound, along with some Austra- 

 lian forms. In the Flora of Sumatra we meet with Rafflesia Arnoldi, 

 Dryobalanops Oaraphora, Sagus Isevis, Stagmaria verniciflua, Rhodo- 

 •dendron Malayanum (top of Sugar-loaf Mountain, Bencoolen, about 

 3000 feet), Vacoinium Sumatranum, Elodea Sumatrana, Millingtonia 

 Sumatrana, Hedychium Sumatranum, and numerous Begonias. The 

 cultivated plants are those of the Indian region (7) ; also, Bread-fruit, 

 Cassava, Nutmeg, Camphor, Papaw, Dammar, Paper-Mulberry, and 

 ■Cotton. 



10. The Region of Upper Java (Blume's Region). — This embraces 

 those districts of the island of Java and the islands of the Indian 

 Archipelago which have an elevation of 5000 to 12,000 feet above 

 the level of the sea. Extra-tropical forms ocour, and the Flora has 

 some resemblance to that of the Emodic region. Ternstroemiacese, 

 Thibaudias, and forests of Podocarpus and Oaks characterise the region. 



11. The Polynesian or Oceanic Region (Ohamisso's Region). — 

 This includes all the islands of the Pacific Ocean within the Tropics. 

 The plants are allied to the Asiatic and Australian Floras. Among 

 the plants of this region may be mentioned Artocarpus incisa, Tacca 

 pinnatifida the Pia, which yields a kind of Arrow-root, Cocos nucifera, 

 Lodoicea seychellarum, Jambosa malaccensis the Ohiaai, and many 

 species of Arum, Dioscorea, Musa, and Ficus. The genera Dissochseta, 

 Orophea, Pterisanthes, Arthrophyllum, and Visenia, occur in this 

 region. In the Sandwich Islands, belonging to the Hawaiian group, 

 nearly one-third of the vegetation is composed of Ferns. There are 

 three Palms, the Coco-nut and two species of Livistona. The rest of 

 the flora consists of Myrtles, Grasses, Sedges, Mimosese, and Arums. 

 Acacia heterophyUa, called Koa, yields durable timber. The root of 

 Dracaena terminalis, called Ki, is eaten. The fruit of Physalis pubes- 

 cens is used ; also the fruit of Pandanus odoratissimus, called Lahala ; 

 that of Osteomeles anthyllidifolia, the Ulei ; that of Morinda citri- 

 folia, the Noni; and that of Morus indica, the Kilica. Colocasia 

 esculenta, the Kalo, is used as a vegetable. Cloth is made from 

 Broussonetia papyrifera and Boehmeria albida, cordage from Paritium 

 tiliaceum, water-flasks from Lagenaria vulgaris; and Macropiper 

 methysticum is the great remedy for diseases. Peculiar Compositse,
